AbstractThe Coast-Intermontane Belt GIS Library is a synthesis of available geoscience information for the east- central portion of the Vancouver (NM-9)map area of southwestern British Columbia. It is designed to be used as an interactive research and/or educational resource for those interested in the geological framework and tectonic evolution of the southwest Canadian Cordillera- the range of mountains that extends northward through Alberta,British Columbia and the Yukon.
The east-central portion of the Vancouver map area encompasses the southern Coast Belt and adjacent parts of the Intermontane and Insular morphogeologic belts of the southwestern Canadian Cordillera. It includes both rugged alpine terrain of the Coast Mountain and Cascade Range physiographic provinces, and adjacent low-relief terrain of the Thompson Plateau, Fraser Lowland and Georgia Depression.
The bedrock foundation for this part of the Canadian Cordillera is a collage of accreted island arc and oceanic crustal fragments, many of which were derived from distant parts of the Pacific Ocean basin and assembled along the ancient continental margin of North America in the early Mesozoic. Since the Early Jurassic (~185 million years ago), these crustal fragments and associated plutonic suites have been structurally imbricated and shuffled along the continental margin in response to subduction-accretion processes and large-scale transcurrent displacements between North America and oceanic crust of the Pacific, Kula and Juan de Fuca plates. Similar processes of subduction, accretion and transcurrent faulting are active today along the boundary between western North America and oceanic crust of the Juan de Fuca and Pacific plates.
Information provided on this CD-ROM represents a synthesis of more than a century of geological mapping and research in the Vancouver (92G), Hope (92H), Ashcroft (92I) and Pemberton (92J) map areas of the southwestern Canadian Cordillera. Collectively, these data provide a foundation for interpreting the history and mechanisms of terrane accretion and crustal deformation that have shaped this segment of the western North American plate margin over the last 200 million years.
